JA Solar JAM54D41 450/LB Full Black Solar Panel Bifacial

Solar PV Module JA Solar JAM54D41 450/LB Full Black — N-type Bifacial Double-Glass Panel

High-efficiency JA Solar bifacial module designed for durable outdoor solar installations, delivering strong performance through low light sensitivity, improved temperature behavior, and long-term power output guarantees.

Applications and use cases

This high-output photovoltaic module is suitable for residential rooftops, commercial rooftops, carport canopies, and ground-mounted solar arrays where space efficiency and energy yield are priorities. Its bifacial double-glass construction captures light from both sides, increasing energy harvest in reflective environments, while the rugged, full‑black aesthetic complements many building styles. The n-type cell technology minimizes light-induced degradation, helping maintain reliable performance across varying climates and sun exposure.

• Rooftop and carport installations for space- and cost-efficient PV systems
• Reflective-site gains from rear-side light capture with bifacial design
• Durable, aesthetically uniform full-black appearance for commercial applications
• Low-LID n-type cells for long-term performance stability
• Compatibility with high-voltage string configurations up to 1500 V
• Excellent performance in low irradiance and hot climates for broader usability

Key electrical and performance parameters

Designed to deliver high energy yield, this module combines a robust electrical package with precise manufacturing traits. The JAM54D41 family provides Pmax variants in the 430–450 W range (430/LB to 450/LB), with Vmpp around 32.1–32.8 V and Voc near 38.5–39.3 V. Isc sits around 14.1–14.5 A, while panel efficiency sits up to about 22.5% depending on the exact variant. Temperature coefficients highlight strong real-world performance: Pmax −0.30%/°C, Voc −0.26%/°C, and Isc +0.046%/°C. The module is built to a maximum system voltage of 1500 V, with a 30 A series fuse rating and IP68-rated junction box housing three bypass diodes. With 108 cells arranged in a 6×18 grid and a weight of roughly 22 kg, this panel balances high power with manageable handling. The product is backed by a 12-year warranty on the module and a 30-year linear power output warranty, underscoring long-term confidence in output stability.
